COATING FOB, SOAP.

Specification of Letters Patent. Patented Dec, 16, 1919.

Application filed January 27, 1919. SerialNo. 273,315.

To all whom it may concern Be it known that I, HARRY J. I-Lmsrr- BERGER,a citizen of the United States, residing at Tippecanoe City, in thecounty of Miami and State of Ohio, have invented certain new and usefulImprovements in Coating for Soap, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to an improved coating for soap, and has for itsparticular ob ect to provlde an improved coatmg for avoiding thepossible dangers of infection resulting from corrosion which is a commonfault of metal soap containers.

To this end I provide a coating ofparaffin applied direct to the body ofthe soap and therefore,- conforming exactly to the shape of the stick.Both ends of the soap,

as well as the cylindrical body portion may be covered with paraffin,but in its preferred form the end ofthe stick from which the soap isused is leftv exposed ready to be used as delivered to the purchaser.

An important advantage is realized in the use of shavlng soap put up inthis manner 1n thatthe paraflin coated stick may be rinsed after usewithout any portion of the soap, except the .exposed end thereof, beingexposed to moisture, the parafiin being impervious to or insoluble inwater at the usual temperature'for'toilet use. Thus the main body of thesoap is kept entirely dry and complete sanitation may be effected.

. It is understood, of course, that shaving soap in the well known formof long cylindrical sticks is applied direct by rubbing the end of thestick over the surface to be lathered, the stick in the ordinarymetalcontainer being pushed upwardly by any suitable arrangement, such as anadjustable bottom in the container. With the use of my improved coatingsuch 7 an arrangement is not necessary, as the ex,-

posed edge of the parafiin will reduceproportionately with the soap inthe application thereof, the, edge of the parafiin coatino re .maimngsubstantially flush with tbeapp ication surface of the soap until theentire stick is consumed.

My invention, obviously, has the advantage of simplicity, cheapness,attractiveness and what is more important convenience and sanitation inuse. Without change or adjustment the soap is always ready for use, andby merely rinsing thestick it is again prepared for after use. .The bodyof the soap'always being dry there is no waste and due to the protectionafforded by the perfectly sanitary parafiin coating there is nopossibility of infectious substances, such as may result from corrodedmetal, being conveyed to the soap. V

An incidental advantage of my invention, made possible by thetransparency of the paraflin coating, consists in the 'means] it affordsfor securing a label or trade mark to the body of the soap, preferablyto the unused end of the soap. The label is not obscured by the paraffincoating over it, and

being protected by the parafiin will be pre- 7 served until the entirestick is used.

The parafiin or coating of other similar materialmay be applied to thesoap in any suitable manner, as by dipping or immersing the cakes ofsoap in a bath of fiuidmaterial whereby an even coating of the materialwill adhere to the soap and when. cooled will condense and form theprotecting coating-as contemplated in the invention. I

Referring tothe drawings,

Figure 1 is'an end view of the paraffin coating as, applied to a stickof shaving soap;

Fig. 2 is a longitudinal cross sectional .view of a stick of soap havingthe paraflinv coating applied thereto;

Fig. 3 is a cross sectional view takenon the line 33 of Fig. 2'; and o x1 .Fig' 4 is an end vi'ew of the invention showing the manner ofsecuringa label to the soap under the parafiin coating.

form of a stick of shaving soap 1, contained within a coatlng ofparaffin 2.

As here shown the invention is in the .Vhile it has'bee'n stated thatone end of the soap 1s preferably left uncoated or exposed, it is, ofcourse, obvious that'both ends may be coated over'with the paraffin, itbe ing then necessary for the user to remove the paraffin from one endof the stick before the first application of the soap is made.

In Fig. a of the drawings the manner of displaying a label or trade markon the soap is shown.

'While paraffin is a suitable material to use to realize the purposes ofthe invention, other materials having similar qualities may also be usedand satisfactory results obtained therewith; the essential qualitiesbeing found in materials that are impervious to water within a normalrange of temperatures; that will conform and adhere to the surface ofthe soap; that will reduce readily with the working surface of the soap;that will keepthe body of the soap dry and protect it against contactwith infectious substances; that will be suitable to serve as acommercial covering for the soap; that will be inexpensive, attractivein ap pearance and convenient and sanitary in use.

Nhile the normally white paraffin in semi-hard or plastic form isordinarily the preferred material to be used, it may be desirable forspecial purposes, as in the preparation of sales or display samples, orto distinguish different grades of soap, etc., to use variously tintedparaflin which would add variety and attractiveness to the soap sticksfor commercial effect.

As far as I am aware 1am the first to discover and apply an inventionhaving essentially the features'of construction and application of thepresent invention. I do not wish to be limited, therefore, to thedetails as herein disclosed and described, but wish to claim broadly, asdefined and comprehended in the appended claims, the principles andessentials of the invention as well as the specific organization andarrangement thereof. The impervious materials as treated inthe claimsare used in a qualified sense having reference to paraffin or likematerial which is normally insoluble to the influence of water, that is,at the temperatures at which water is ordinarily used for toiletpurposes.

Having thus fully described my invention,

What I claim as new and desire to secure by Letters Patent, is

1. The combination, with a cake of soap having an end adapted to beimmersed in water from which the soap is applied by rubbing the same onthe skin to be treated thereby, a coating of impervious material formedintegral of said cake and terminating in edges substantially flush withsaid end portion, and reducible equally with the surface thereof in theapplication of said soap.

2. The combination, with a stick of soap, a coating of imperviousmaterial covering the body and one end thereof adapted to pr-vent soapcoming in contact with the hand and terminating in an edge substantiallyflush with the opposite end of said stick, and reducible equally'withsaid end in the application of soap therefrom.

3. The combination, with a stick of shaving soap, a coating ofimpervious material covering the body and one end thereof adapted toprevent soap coming in contact with the hand and terminating in an edgesubstantially flush with the opposite end of said stick and reducibletherewith incident to a rubbing application of said end to the skintreated thereby.

4c. The combination, with a stick of shaving soap, a coating ofsemi-plastic impervious material covering the bodyand one end thereofadapted to prevent soap coming in contact with the hand and terminatingin an edge substantially flush with the opposite end of said stick andreducible therewith incident to a rubbing application of said end to theskin treated thereby.

5. The combination, with a stick of shaving soap, a coating ofsemi-plastic impervious material conforming and adhering to the body andone end of said stick and terminating in an edge substantially flushwith the opposite end of said stick and adapted to be immersed in waterreducible therewith incident to a rubbing application of said end to theskin treated thereby.

In testimony whereof, Tafiix my signature.

HARRY J. HARSHBERGER.
